I would like to download your map of the Caribbean on to my Garmin Handheld GPS (eTrex Legend). I got stuck on your first paragraph of instructions where it said, "Unzip the map file that you downloaded from this site. You will have a file called gpsapsupp.img". I'm a novice at this sort of thing. First I was unaware that I had downloaded a zipfile and if I had I have no idea where to look for it, or what to do to unzip it and install it in my blank 2GB microcard inserted in my Garmin GPS. Sorry to be a pain. FJB
